As a promising battery material, tungsten disulfide is also expected to benefit from more market supplementation

wallpapers News 2021-07-16
Lithium-ion batteries are the key raw materials for the development of energy equipment and the realization of the vision of "carbon neutral". However, as a matter of fact, the current capital investment in the raw material side is difficult to cover the rapidly growing energy demand. There is an obvious structural imbalance in the investment in the lithium industry chain, and the shortage of supply leads to the rising cost of lithium raw materials.
 
As a promising battery material, tungsten disulfide is also expected to benefit from more market supplementation. Tungsten disulfide is a layered material with remarkable surface effect, electron fluidity, thermochemical stability and high electron density of state. It has a wide range of applications in lithium and sodium storage fields. For example, nanocomposites as conductive additives or graphene composites as anode materials of batteries can show higher specific capacity and discharge efficiency, making up for the lack of single-component WS2 or C as anode materials.
 
Graphene is the most energy storage researchers in recent years a new anode material, it has many advantages, such as excellent conductivity and thermal conductivity, large specific surface area (2630 m2 / g), etc., but as the energy storage material is difficult to offset its own disadvantages, such as the material under the long cycle of structure collapse easily happen, and, in turn, to cause a decline in battery capacity is serious, Therefore, composite with WS2 nanomaterial with high thermal chemical stability can effectively make up for the shortcomings of graphene.
 
In general, tungsten disulfide material is the ideal choice of battery material. Under the influence of the expected development of 5G base station, energy storage power station, electric bicycle and other downstream industries, the demand for tungsten disulfide may usher in a new inflection point.
 
It is understood that the shortage of the existing production technology and production equipment maturity the sodium ion battery energy density is far less than the density of lithium-ion battery, so the application of high-end models have limitations, but in the field of energy storage market and small power strong alternative, such as communication station, energy storage power station, electric bicycle, electric vehicles at low speed, etc.
